No. Hand tracking runs on your device inside the browser. Video frames are processed locally and never sent to a server. Your drawing and settings are saved in your browser's local storage only.

Not to draw. Mouse, touch and pen all work, right-click drag erases, and holding Shift while dragging conjures shapes. A webcam unlocks drawing in the air and the two-hand mode.

AirDraw Studio is developed and tested in Chromium-based browsers such as Chrome and Edge. Current Safari and Firefox should work but are less tested. A camera and HTTPS (or localhost) are required.

If access was blocked, click the camera icon in the address bar, choose Allow, and press Try again. If another app (a video call, for example) is using the camera, close it first. You can also pick a different camera in Settings once one is running.

Open Settings. Raise Pinch sensitivity if pinches don't register, lower it if they trigger too easily. If you're drawing with your index finger, curl it fully to lift the pen. Good, even lighting on your hand helps a lot.

Point is easiest for writing and is the default. Pinch gives crisper start and stop for fine detail. Switch any time in Settings.

Show both hands to the camera. A ghost of the chosen shape appears. Pinch thumb and index on both hands, pull apart to resize, and release a pinch to place it. Choose Matrix, Frame, Orb, Star or Bolt from the bar above the toolbar.

Use Save in the top bar for a PNG (switch on Transparent PNG in Settings for a cut-out) or Record to capture a video of the canvas. Your drawing also autosaves in this browser.

Yes. Undo and redo cover strokes, erasing, Clear and conjured shapes. Use the toolbar or Ctrl/⌘ Z.

Touch and pen drawing work. Camera hand tracking on mobile browsers is untested, so expect it to be slower or less reliable than on a laptop.
